WILLIAM H. MILLER, OF SPRINGFIELD, MASSACHU MAGNETIC SHUTTLE-MOTION FOR LO OMS;

SPECIFICATION forming part of Letters Patent No. 773,010, dated October 25, 1904.

I Application filed July I5, 1902. Serial No. 115,713- (No modem To all whom it may concern:

Be it known that I, HENRY STREET FUR- MINGER, a citizen of the United States of America, residing at Mittineague, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Looms, of which the following is a specification. v

This invention relates to improvements in looms; and it has especial reference to the construction of the shuttle-operating mechanism whereby the picker sticks may be done away with; and the object of the invention isv to provide improved means for propelling a shuttle transversely of the warp-threads by electrically operated means, the invention .consisting 1n improved devlce'scarried on the loom having my invention applied thereto.-

Fig. 2 is an enlarged plan view of the carrier by means-of which the magnet may be reciprocally operated. Fig. 3 is a perspective view of a part of the lay-beam and the devices carried thereon for moving the shuttle,

a perspective View of a piece of woven fabric and of a movable finger, around the end of which a weft-thread is drawn temporarily during the movement of the shuttle.

In the drawings forming part of this application no particular form or type of loom has been shown, and the various elements of the machine, except such asrelate to the invention, may be considered as purely conventional. y

In the drawings, a indicates the frame of a loom; b, the heddles; c, a cam-shaft driven by a suitable belt, there being cams on said shaft, (which will be described farther on,) whereby the lay-beam CZ may be given the Fig. 4 is proper reciprocatory movements to beat up the fabric. On another cam-shaft, 0, there is a cam f, whereby the levers g, connected to the heddles Z), may be operated to impart to 'said heddles proper alternate reciprocatory movements in a vertical plane to effect the separation of the warp thread. .Mounted upon the lay-beam (Z is the reed-frame it.

The lay-beam 0Z slides in a horizontal plane on two tracks 71, secured to the frame a,-as shown in Figs. 1 and 3, there being suitable shoes 1' bolted to the ends of the beam, which fit over said tracks and support the beam. This beam is given reciprocatory horizontal movements on said tracks by means of a connecting-arm is, pivotally connected to Said beam and to the end of an arm m, pivotally riage q is a hanger t, which supports a rockshaft 15, each end of which is bent at right angles to the shaft in opposite directions in substantially the same plane, constituting arms whereby the shaft 20 may be rocked, and on this shaft there is secured in any proper way a downhanging arm 0), whose lower extremity is provided on two opposite sides thereof with the vertical ribs 10.

Beneath the layebeam and carried thereby in suitable bearings are two vertical shafts y, (shown in Fig. 2,) carrying sprocket-wheels 2, over which runs the belt 3, whose inner surface is provided with vertical ribs l, which engage with the teeth of the wheels 2', one of which is driven by the belt 5 (shown in Figs. '1

and 2) and which runs from an overhead counter-Shaft over idler-pulleys 6, thence horizontally around a pulley on one of the shafts y.

This disposition of the belt 5 permits the laybeam (Z to move on its carriage while said belt imparts suitable continuous movement to the belt 3.

As seen in Fig. 2, the two shafts 1 are offset for a distance equal to about half the diameter of the wheels 2, and idler-pulleys7 are applied to the opposite sides of the belt, as shown in said Fig. 2, whereby while the two sides of the main portion of the belt are parallel there is a space at each end where one side of the belt takes an angular course relative to said parallel courses. The object of this belt construction is for this purpose: 1V hen the arm '0 is, by the movements of the rock-shaft n, swung into engagement with either one or the other sides of said belt and held in such engagement, the carriage q will be slid along the tracks 3) so long as that engagement continues.

Assuming the parts to be in the position shown in Fig. 2, it would be first swung into engagement with the farther side of said belt 3, (the direction of whose movements 1s shown by the arrow above the belt,) said arm remaining in such engagement until it arrives at a point opposite the pulley 7 over which that side of the belt runs, and at this point, by reason of the direction taken by the belt, the engagement with said arm 4; will be severed and the movement of the carriage q will be arrested. This will leave the arm *0 in the same position relative to the oppositeend of the belt that it now occupies in Fig. 2. The means whereby the arm 2; may be operated to be swung alternately into engagement with opposite sides of the belt 3 consist in providing on the frame of the machine suitable abutments against which the crank-shaped ends of the rock-shaft u may strike upon the return movement of the lay-beam to the position shown in Fig. 1 after having been moved forward to bear up the work.

In Fig. 3 the position of the parts is that which they would occupy before the lay-beam has returned to its rearmost position after its beating-up movement, at the completion of which movement the turned-down end of the rock-shaft (shown in dotted lines only) will come into contact with the arm 8, and the arm a; be thus swung to the opposite side of the belt 3. The carriage q will then be moved transversely of the work, as described, the lay-beam going forward to beat up after the conclusion of the shuttle movement, and upon its return the upturned end of the rock-shaft on the side nearest the observer, as shown in Fig. 3, (which will then be inclined toward the rear of the machine,) will come in contact with another arm 9, which is shown only in dotted lines in Fig. 1, which contact will again shift the arm o to the opposite side of the belt to effect the return movement of the shuttle.fThe electromagnet is connected with a suitable source of electricity by wires 10, said source being indicated by 12 in the conventional manner of representing a. battery constitutiuga closed circuit in which the magnets w are normally energized. Any other source of electricity of course is equally effective. The wires 10, which run to the magnet, are of course of sufficient length to follow the movements of the carriage 1 The warp-threads are indicated by 13 in the drawings and are shown only in Fig. l. The shuttle is indicated at 1 1 and is shown in full lines only in Fig. 1 and in dotted lines in Fig. 3. Said shuttle is made flat on the under side thereof and preferably is semicircular in cross-section and pointed ateither end in the usual manner.

Mounted on a suitable standard between the tracks p is a shuttle-box 15 at each end of said tracks and adapted to receive the shuttle at the termination of its traverse movement.

The operation of this machine is as follows: The warps having been duly set up in'the usual manner and the shuttle provided with wellthreads and placed in one of the boxes to, the carriage 71s moved into proper position beneath said box and movementimparted to the belt 3. The arm n may then be operated by hand and swung into connection with the proper side of the belt 3 to start the carriage g on its traverse motion, the magnets 1' having sufficient power to carry the shuttle 14: across the warp-threzuls as themagnets move back and forth under the same. After each transverse movement of the carriage preferably the lay-beam (if is moved forward on its tracks to beat up the weft-thread last drawn across the fabric by means of the usual reeds 72/, the heddles being operated as desired by the cams f on the shaft e and the beam (Z being operated by the cams 0,1011111') movements being imparted to the shaft e by means not shown. The shuttle in its traverse'movemcnt might on certain classes of goods draw the weft-thread up too tightly on each selvage edge of the fabric, and to obviate this there is provided on each side of the machine a pivoted linger 16, (suitably supported on the frame, as shown in Fig. 1,) one on each side of the work, in such position that the upturned end 17 of said lingers will lie close to the edge of the fabric and project somewhat above it in such position that when the weft-thread is beaten up the lower end of said linger 16 will be struck by some part attached to the lay-beam (I, whereby the end 17 will be depressed and the last weft-thread moved over said end against the body of the fabric. Then when the beam retires said end 17 comes up behind said last weft-thread, as shown in Fig. 4, and when the shuttle moves back across the fabric the end 17 of the linger 16 holds the weft-thread against the drag of the shuttle, whereby a. uniform selvage edge is formed on the fab- The end 17 of the finger 16 remains in other.

engagement with the last weft-thread until the beam again goes forward to beat up an- This finger 16, however, and its operating devices do not constitute a part of the present invention, but are to form the subject-matter of a separate-application.

While certain specific devices have been described herein as means for shifting the arm is from one side to the other of the belt 3, I do not wish it to be understood that I confine myself to these devices as described and shown, for they are but unimportant features of the invention, and other means to effect the.

shifting of this arm which will have the same functionmay be used. a I

I The designation of the'warp and weft as "threads is purely conventional. The ma chine may be used to weave wire-cloth or other 'fabrics than those composed of fibrous material and generally designated as threads.

Having thus described my invention, what I claim, and desire to secure byLetters Patent of the United States, is
